Application April 14,

4 Claims.

The invention relates to a device for locking cooperating sliding sash of a window in relatively fixed relation while" the window is open.

' The present application is a refile, in part, of 5 my abandoned application filed on July 19, 1929,

Serial No. 378,255, allowed on May 23, 1930.

An object of the inventionis to provide a device of the character described which is applicable as an attachment for sash fasteners of a ccmmon cam-lever and hook type without changing the latter.

Another object of the invention is to provide a device of the class described which permits relative adjustment between the sash while open and is controllable only from the inside of the window.

A further object of the invention is to provide a device 'of the character, described having all parts thereof arranged for releasable mounting 20 in operative position whereby the device may be moved from window to window for use where and as desired.

Still further it is proposed to provide the member with a top laterally upwardly extending grip 5 portion which is adapted to rest against the pane of glass and dig into the glass for breaking the same when the window is being forced open with the lock closed.

Still further it is proposed that the clatter of the breakingglass notify persons in the vicinity that someone is attempting to break through the window and so frighten theintruder away.

,Yet'another object of the invention is to provide a device of the class described having a new combination and correlation of parts whereby marked economies in manufacture will be affected and the efficiency of the device-will be enhanced. The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth or be apparent in the following description of a preferred form of the invention which is illustrated in the accompanying drawing, in which:

The present invention particularly concerns the structure of a sash securing device 8 for removable engagement with the cooperating elements of sliding-sash fasteners of a usual type whereby the sash may be secured in open position. As particularly illustrated, the elements of such a sash fastener are disclosed in operative association with cooperating upper and lower sash 9 and II) of a window, and comprise a hook member I I fixedly mounted at the top side of the lower rail I2 of the upper sash 9 and a lever member I3 rotatably mounted at the top side of the upper rail I4 of the lower sash I0. As is usual, the hook of the member I I opens toward the sash rail I2 which carries it, and the lever I3 is wedgedly engageable with the member II when the window is fully closed to simultaneously lock the sash 9 and Ill together and forcibly engage them with the opposite window frame ends.

In the present instance, the lever I3 is seen to be in the general form of a semi-circular plate and is pivotally mounted on an elongated base member I5 for rotation in its plane about an axis which is transverse to the rail I4, said base member being fixed to and along the latter rail opposite the line of movement of the hook II. As is usual, the hook engaging portion of the lever is arranged to be swung to overlie the rail 9 of the upper sash for engagement in the hook II, or may be retracted to permit the free movement of the sash, said lever portion in the latter case extending rearwardly of the base I5 whereby it directly overlies the rail 9 in spaced relation therefrom. As particularly disclosed, a flange I6 extendstransversely upwardly from the plate I3 along the arcuate rim thereof, said flange providing an inclined upper edge for engagement in the hook I I and terminating at its higher end in a radially extending handle I! for effecting a rotative displacement of the lever. In the present instance, the lever I3 is seen to constitute a cam plate, it being noted however, that in some sash fasteners with which the device 8 is arranged to be used, the oblique wedging surface is provided by the hook rather than by the looking lever which engages it.

Referring now to the specific structure and use of the fastening device 8 which constitutes the present invention, it is seen that said device comprises a rod member I8 which slidably carries thereon an arm member IS. The lower end of the rod i8 is formed to provide an eye 2| for receiving the upper portion of the hook I l in such manner that when the rod extends generally upwardly from the hook, it may not be disengaged therefrom by a longitudinal displacement thereof and so is hingedly fixed to the hook for movement with the sash. The arm !9 is seen to comprise an outer end portion 22 perforated adjacent its free end to slidably receive the rod It, an intermediate depending portion 23, and an inner portion 24 shaped and otherwise arranged for engagement with the inner side of the base l5 and beneath the plane of movement of the lever for imprisonment beneath said lever. As shown, the inner base portion is frusto-conically curved, and the arm portion 24 for engagement therewith is therefore complementarily arcuate, said portion having one end fixedlto the lower end of the arm portion 23. Preferably, and as shown, the arm !9 is so constituted as to provide the portions 22, 23 and 24 thereof in integral assoc1ation, as is particularly disclosed. A knob 25 at the upper end of the rod I8 is provided as a means for retaining the arm on the rod, the removal of said arm being at no time necessary; The portion 22 is also formed with a top laterally upwardly extending grip portion 22 which normally rests against the pane of glass 62' to break the same when the sashes are being forced open with the lock closed.

The perforation 26 of the arm [9 which receives the rod I8 is preferably formed to have sharp end edges and said perforation is ofsuch size that a rocking of the arm longitudinally of the rod will effect a binding grip of the rod by the arm, the relation being particularly brought out in Figure 5. It is noted that a slightly rocking fit of the arm portion 24 beneath the overlying lever portion and against the rail I4 is provided whereby a longitudinal movement of the rod I8 either upwardly or downwardly from an intermediate position thereof transverse to the rod will provide the aforesaid binding grip of the rod and so secure the sash against relative movement while permitting their joint movement. Relative movement of the sash may, of course, be effected by disposing and holding the arm in said intermediate position while adjustment is made. are seen to be disclosed in Figure 5, one looking position of the arm being shown in dash lines. It will now be clear that relative movement of the sash to open the window from the outside is positively prevented and that the present device is particularly useful for preventing the unauthorized further opening of open windows to permit the entrance therethrough of burglars or prowlers.

To permit the mounting of the present device in the hereinbefore described operative position thereof, the rod 18 is provided with an off-set portion 21 whereby to define a notch 23 therein extending transversely of the plane of the rod and its eye 2!. To effect the mounting of the device, both sash are first placed inv window closing positions with their rails 9 and In in opposition and the fastener hook and lever disengaged. The rod eye 2| is then engaged with the hook I I, and the rod disposed in upright position above the hook, the notch 28 of the rod being directed inwardly. One or both of the sash are then displaced to effect a disposal of the notch 28 opposite the plane of movement of the lever it and said lever is then turned to or toward a locking position there- The two locking positions of the arm l9- of such that it no longer overlies the sash rail l4 inwardly of its supporting base IS, the notch 28 being specifically provided to permit such disposal of the lever by receiving its protruding portion. The arm l9, which has up to now been held above the level of the lever, is lowered to engage its inner portion 24 generally around the base 15 at the inner side thereof, it being noted that the arm portion 22 overlies the lever and is just long enough to permit the disposal of the portion 24 behind the base IS. The specific disposal and relations of the various elements involved are seen to be particularly disclosed in Figures 6 and 7 of the drawing.

With the various elements disposed as now described, the lever I3 is turned toward its unlocking position to position its arcuate rim over the arm portion 24 and at the same time remove said rim from the rod notch 28. The arm may now be held to dispose its portion 22 in its intermediate rod releasing position and the sash relatively shifted to desired relation, whereupon the arm would be released to thereafter prevent such shifting by reason of its rod gripping operation in the manner previously described. Preferably, and as shown, the end of the flange H5 at the handle I! is arranged to engage, or substantially engage, the arm portion 23 when the other flange end just clears the rod I8 whereby the rod operates toprevent an inoperative displacement of the lever with respect to the underlying arm portion 24 except when the notch is in coplanar relation to the lever, the latter relation being necessary for effecting a removal of the fastening attachment now described. Figures 3 and 4 are seen to disclose the aforesaid relations with particular clarity. V g

In view of the foregoing, it will be obvious that the fastening device 8 is essentially an attachment for existing window catches whereby a window may be safely left open. Furthermore, the device may be carried by travellers for almost universal use on windows of different rooms as may be desired or required, whereby to promote both the health and safety of the traveller.

Fro-m the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and

while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made,

when desired, as fall within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

1. In combination with a sash fastener comprising hook and lever members for mounting on different sash for cooperative engagement to retain the sash in window closing position, a rod element having an eye to receive said hook, an arm element slidably mounted on said rod and arranged for releasable retention by said lever, and means operative upon a rocking of said arm in the common plane of the arm and rod to fix the arm to the rod against movement therealong.

In combination with a sash fastener comprising hook and lever members for mounting on different sash for cooperative engagement to retain the sash in window closing position, different elements for releasable engagement with said members for movement therewith, and means for adjustably fixing said elements together whereby to retain the said sash in adjusted fixed relation.

3. In combination with a sash fastener comprising hook and lever members for mounting on different sash for cooperative engagement to retain the sash in window closing position, a rod element having an eye to receive said hook, an arm element slidably mounted on said rod and arranged for releasable retention by said lever, means including said rod to normally prevent the release of said .arm from its retained engagement with said lever, and means releasably fixing said rod and arm in adjusted relation.

4. A sash fastener, comprising a hook member for mounting on a slidable sash, a rod element having an eye engaging upon said hook member and said rod element normally extending upwards at a slight inclination with relation to said sash and pivotal towards and away from said sash, a lever member for mounting on a second sash which is slidably mounted adjacent said sash, an arm element pivotally mounted on said lever member and having a perforation formed therein with vertical sides and through which said rod element passes with its sides resting against opposite sides of said perforation to pivot said arm element downwards to produce a binding I grip between said rod and the edge portion of said perforation, and an upwardly extending grip portion formed on said arm element for normally bearing against a pane of glass mounted in said sash having said hook member to break the same when said arm element is pivoted downwards by an attempt to force said sashes.
